5. Setup
5.1 Charging the Device
The HP-886A is equipped with a built-in 1100mAh lithium battery. To charge the device, connect the provided USB Type-C cable to the Type-C charging port on the side of the detector and to a standard USB power source (e.g., computer, wall adapter).
5.2 Power On/Off
- To Power On: Short press the 'OK' button. The device will boot up and display real-time radiation data.
- To Power Off: Long press the 'OK' button until the screen turns off.
6. Operation
6.1 Basic Measurement
Once powered on, the device will immediately begin detecting radiation and displaying real-time data on the LCD screen. The display shows current dose rate, maximum value, average value, current alarm threshold, cumulative dose equivalent, temperature, and humidity.
6.2 Switching Display Modes
Short press the left or right arrow buttons to switch between the real-time data display and the trend graph display. The trend graph provides a visual representation of radiation levels over time.
6.3 Accessing Settings Menu
To enter the settings menu, long press the 'OK' button. Once in the menu:
- Use the up (▲) and down (▼) arrow buttons to navigate through the settings options.
- Use the left (◄) and right (►) arrow buttons to switch between different settings values or sub-options.
- Short press the 'OK' button to confirm a selected setting.
- Long press the left (◄) arrow button to return to the previous menu or exit the settings.

7. Alarm Functions
The HP-886A detector supports both current alarm and cumulative alarm thresholds. These thresholds can be set by the user in the settings menu. When detected radiation levels exceed the preset thresholds, the device will activate one or more of the following alarm modes:
- Light Alarm: The LED indicator on the device will flash.
- Vibration Alarm: The device will vibrate.
- Sound Alarm: An audible alert will be emitted.
8. Wide Applications
The HOLDPEAK HP-886A Nuclear Radiation Detector is suitable for a wide range of applications where radiation monitoring is necessary. This includes, but is not limited to:
- Monitoring for nuclear fallout.
- Checking for contaminated food and water sources.
- Use in radiology departments and medical radiation environments.
- Detection of radioactive rocks and materials.
- Industrial radiation monitoring.
9. Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the device. Do not use abrasive cleaners or solvents.
- Storage: Store the detector in a cool, dry place, away from direct sunlight and extreme temperatures. When not in use for extended periods, ensure the battery is partially charged (around 50%) to prolong its lifespan.
- Handling: Handle the device with care. Avoid dropping it or subjecting it to strong impacts, as this can damage the sensitive internal components, especially the GM tube.
10. Troubleshooting
- Device does not power on: Ensure the battery is charged. Connect the device to the USB charger and try again.
- Inaccurate readings: Ensure the device is not exposed to strong electromagnetic interference. Calibrate the device if necessary (refer to advanced settings in the full manual).
- Alarm not working: Check alarm settings in the menu to ensure they are enabled and thresholds are set appropriately.
- Screen is blank or frozen: Try restarting the device by long-pressing the 'OK' button. If the issue persists, contact customer support.
11. User Tips
- The HP-886A uses an Energy Compensation GM Tube for detection. This type of tube is known for its reliability in detecting beta, gamma, and X-rays.
- When taking measurements, try to keep the detector as close as possible to the suspected radiation source for the most accurate readings.
- Familiarize yourself with the different dosage units (μSv/h, μGy/h, mR/h, CPS, CPM) and select the one most appropriate for your application.
